JOHN G. HAUSSLER, OF POTTSVILLE, PENNSYLVANIA.

SILK-FEEDING HOOK ATTACHIVIENT FOR SEWING-MACHINE NEEDLE-BARS.

To all whom it may concern:

Be it known that 1, JOHN C. HAUssLER, a citizen of the United States,residing at Pottsville, in the county of Schuylkill and State ofPennsylvania, have invented certain new and useful Improvements in Silk-Feeding Hook Attachments for Sewing-Machine Needle-Bars, of which thefollowing is a specification.

My invention relates to an improved silk feed hook-attachment for sewingmachine needle bars, the object of the invention be ing to provide animproved detachable hook, which can be readily placed in position upon aneedle bar, and which will so regulate and control the feed of silk tothe needle as to prevent frequent breaking of the silk, as is the casewith attachments now in use.

There is in common use, a hook-attachment for sewing machines, whichcomprises a single wire hook extending around the needle bar, and underwhich the silk passes in its movement to the needle. This single hookmerely acts as a guide for the silk, and does not in any way control thefeed, but merely prevents the silk from flying outward from the upperend of the needle bar to the neodle. With such a hook the silkfrequently accumulates in considerable quantity about the needle, andbecomes more or less knotted, so that the quick reciprocation of theneedle will break the silk. To prevent this my improved attachment wasdevised, as will be more fully hereinafter explained.

In the accompanying drawings, Figure 1, is a view in elevationillustrating the appli cation of my improvements to a sewing machineneedle bar. Fig. 2, is a view of the device removed. Fig. 3, is a viewof the device before bending.

1 represents an ordinary needle bar, having a needle 2 secured thereinby means of the clamping screw 3, and 4 represents my improvedattachment, which comprises a single piece of wire bent at a pointmidway between its ends forming an eye 5, and the latter flattened atits sides so as to engage smoothly against the needle bar 1, to receiveSpecification of Letters Patent.

a clamping screw 6 and securely clamp the attachment to the needle bar.

The ends of the wire are curved around the needle bar as clearly shown,and the silk 7 is passed inside of the upper hook and outside of thelower hook, and then down through the eye of the needle 2. When myimproved attachment is employed around a needle bar, the two wire hookswill exert a breaking action of the silk passing between them, so as tosulliciently retard the feed of silk and allow just the proper amount tobe drawn to the needle as the latter reeipro cates, and will prevent anaccumulation of silk at the needle, where it would become knotted andbroken by the movement of the needle.

The spring hooks are sufliciently elastic and flexible, so as not toretard the feed of silk to any material extent, but only just enough toprevent an accumulation of silk at the needle. The single hook inordinary use, either binds the silk against the needle bar, or elseallows such a large quantity to pass through, that its accumulation atthe needle results in the breaking of the silk, and my improvementsthough extremely simple, are a vast improvement over the single hookconstruction as has been demonstrated in practical use.

Slight changes might be made in the general form and arrangement ofparts described without departing from my invention, and hence I do notrestrict myself to the precise details set forth, but consider myself atliberty to make such changes and alterations as fairly fall within thespirit and scope of the claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

1. As an article of manufacture, a double hook attachment for sewingmachine needle bars, adapted to be positioned around the needle bar of asewing machine.

2. As an article of manufacture, a double hook attachment for sewingmachine needle bars, comprising a single wire bent between its endsforming two hooks adapted to be positioned around the needle bar of asewing In testimony whereof I have signed my machine. name to thisspecification in the presence of 10 3. As an article of manufacture, adouble two subscribing witnesses.
